This is a layered photoshop file of a metal base I've painted 100%from scratch. You can easily take out layers, and mess with the blends and such, to get the results you want. It is a 1024x1024 size, though you'll probably want to re-size it to better match the texture you've working on (this is sized to look about right if you did a helmet texture at 1024x1024, for example).

My aim here was to make something similar to the textures used in a lot of the Native stuff (ex. helmets) for people to use on their own stuff, to help them blend in easier.This is mostly intended for people who don't know where to start with creating their own textures.

I haven't actually tried using this on anything yet, so feedback is welcome.
